Abstract

A radio-on-hybrid wavelength-division-multiplexing (WDM) transport system based on distributed feedback laser diodes and semiconductor optical amplifiers with double external light injection techniques is proposed and demonstrated. Good performances of bit-error rate, modulation-error ratio, carrier-to-noise ratio, error vector magnitude, and third-order intermodulation distortion-to-carrier ratio were achieved in our proposed systems. This demonstrated that such a radio-on-hybrid WDM transport system is attractive for 256-quadrature amplitude modulation/gigabit Ethernet, 2.4-GHz/local area network, and 5.8-GHz/intelligence transport system signals.
